Abstract

The invention relates to an umbrella, characterized by the wind safety system thereof, the triggering device of which is located in the area where the pole (2) of same contacts the ground, or directly on the shaft thereof, as the case may be, and which includes a return device consisting of a slider (4) having a spring (5), and then a flexible transmission assembly connecting the head of the slider to a retracting mechanism of the closing trigger (9) of the umbrella, whereby, when pressed against the ground, the weight of the umbrella crushes the spring (5), the slider (4) is in the top cocked position, and then, as soon as the wind tends to raise the umbrella, said pre-stressed spring expands and pushes the slider back down, thereby tensioning the transmission element and causing the trigger (9) to retract, in order to finally ensure automatic closure of the umbrella. In the case where said umbrella includes a pole, same is made in a reverse telescopic configuration, i.e., with the sliding strand having a small diameter at the bottom portion, which, for storage purposes, is completely retracted into the shaft (1), the locking system (3) next being actuated in order to immobilize the pole, the entire assembly offering an optimal storage configuration without any risk of the pole being mal-positioned.

Description

PARASOL DE SECURITE POUR LE VENT, A DECLENCHEMENT PAR LE BAS  SAFETY SUN UMBRELLA FOR THE WIND, LOW TRIPPED
La présente invention concerne un parasol équipé d'un système de sécurité pour le vent, qui se déclenche par un actionneur localisé au bas de son appui direct avec le sol. The present invention relates to an umbrella equipped with a safety system for the wind, which is triggered by an actuator located at the bottom of its direct support with the ground.
Généralement les parasols sont constitués de deux éléments séparés : d'une partie supérieure comprenant le mât et l'ombrelle, puis d'une pique en partie inférieure. Il existe également des parasols sécurisés pour le vent par un système de fermeture automatique dont le déclenchement est initié par la tête lorsqu ils retombent sur le sol après avoir été emportés par une rafale. Ces types de parasols sécurisés sont généralement bien adaptés à une utilisation sur les plages. En revanche lorsque le parasol est utilisé en terrasse ou sur une table, et lorsqu'une rafale de vent tend à le soulever il est important que celui-ci se referme rapidement par sécurité pour éviter le renversement de la table.  Generally umbrellas consist of two separate elements: an upper part comprising the mast and the umbrella, then a spade in the lower part. There are also sunshades secured to the wind by an automatic closing system whose triggering is initiated by the head when they fall on the ground after being carried away by a gust. These types of secure parasols are generally well suited for use on beaches. On the other hand, when the parasol is used on the terrace or on a table, and when a gust of wind tends to lift it, it is important that it should close quickly for safety so as to prevent the table from overturning.
La présente invention permet très simplement de résoudre ce problème en intégrant un mécanisme à ressort au bas de la pique du parasol ou tout simplement de son mât de sorte qu'un léger soulèvement de celui-ci suffise à déclencher sa fermeture. De plus l'invention reste applicable à une pique télescopique à coulissement inversé, c'est-à-dire qu'elle est la partie mâle et le mât la partie femelle, offrant ainsi deux avantages majeurs : d'une part aucun mécanisme n'est apparent à l'extérieur et d'autre part pour le stockage ou le transport du parasol, la tige télescopique rentre entièrement dans le mât ce qui est plus pratique et moins encombrant.  The present invention makes it possible very simply to solve this problem by integrating a spring mechanism at the bottom of the sunshade spike or simply of its mast so that a slight lifting thereof is enough to trigger its closure. Moreover the invention remains applicable to a telescopic spike with inverted sliding, that is to say it is the male part and the mast the female part, thus offering two major advantages: on the one hand no mechanism n ' is apparent outside and on the other hand for storing or transporting the umbrella, the telescopic rod returns fully into the mast which is more convenient and less cumbersome.
DESCRIPTION TECHNIQUE TECHNICAL DESCRIPTION
Le parasol selon l'invention comprend essentiellement le mât Rep.l supportant l'ensemble des éléments que l'on retrouve dans les parasols conventionnels: baleines, corolle, tissus, poignée et verrouillage, en partie inférieure un brin télescopique Rep.2. qui assure la fonction de pique du parasol, un système de blocage Rep.3, un coulisseau Rep.4 avec ressort de rappel Rep.5, une chaîne à billes de transmission d'effort Rep.6, une corde à piano Rep.7, une came Rep.8 montée sur la gâchette de verrouillage Rep.9 et son ressort de rappel Rep.10. La Fig.l montre le parasol ouvert en configuration d'utilisation, avec sa pique déployée, et le système de déclenchement armé. The parasol according to the invention essentially comprises the mast Rep.l supporting all the elements found in conventional umbrellas: whale, corolla, tissue, handle and lock, in the lower part a telescopic strand Rep.2. which provides the parasol spike function, a blocking system Rep.3, a slide Rep.4 with return spring Rep.5, a ball chain transmission of effort Rep.6, a piano string Rep.7 , a cam Rep.8 mounted on the locking trigger Rep.9 and its return spring Rep.10. Fig. 1 shows the open umbrella in use configuration, with its deployed spike, and the armed release system.
La Fig.2 montre le parasol légèrement soulevé par le vent, avec son système de sécurité activé qui déclenche le déverrouillage et donc la fermeture du parasol.  Fig.2 shows the parasol slightly raised by the wind, with its activated safety system that triggers the unlocking and therefore the closing of the parasol.
La Fig.3 montre le parasol en configuration de stockage ou de transport lorsque la pique est rentrée à l'intérieur.  Fig.3 shows the umbrella in storage or transport configuration when the spades are tucked inside.
La Fig.4 montre une application de l'invention sur un parasol sans pique s'appuyant directement sur son mât.  Fig.4 shows an application of the invention on a sunshade without spike leaning directly on its mast.
La Fig.l est une vue en coupe montrant un exemple de réalisation d'un parasol équipé d'un système de sécurité pour le vent qui déclenche au bas de sa pique télescopique. Ce parasol est verrouillé comme tout parasol par la gâchette Rep.9 assurée par son ressort de rappel Rep.10. Sur cette gâchette, à l'intérieur du mât, une came Rep.8 pivote lorsqu'elle est actionnée de manière excentrée par une corde à piano Rep.7. La géométrie de cette came est définie de sorte que sa zone concave vienne en contact sur la paroi interne coté gâchette et que lorsqu'elle est mise en tension vers le bas par la corde à piano, son mouvement circulaire s'accompagne d'une translation entraînant la gâchette vers l'intérieur induisant la fermeture automatique du parasol.  Fig.l is a sectional view showing an embodiment of an umbrella equipped with a safety system for the wind that triggers at the bottom of its telescopic pole. This sunshade is locked like any sunshade by the trigger Rep.9 ensured by its return spring Rep.10. On this trigger, inside the mast, a cam Rep.8 pivots when it is operated eccentrically by a piano string Rep.7. The geometry of this cam is defined so that its concave zone comes into contact on the inner wall trigger side and that when it is tensioned down by the piano wire, its circular movement is accompanied by a translation causing the trigger inward inducing the automatic closing of the umbrella.
Au bas de la pique est emmanché un fourreau Rep.ll contenant le système de déclenchement constitué du coulisseau Rep.4 avec le ressort de rappel Rep.5, le tout refermé par le couvercle Rep.12 bloqué par la vis Rep.15. Le guidage en translation du coulisseau est assuré par la vis Rep.14 dont le tenon d'extrémité est logé dans la rainure Rep.20. Une chaîne Rep.6 réalisée par une série de maillons ou de rotules articulées ou de billes transmet le mouvement de la tête du coulisseau au bas de la corde à piano. Cette configuration de maillons faits de rotules articulées entre elle, offre l'avantage d'une parfaite souplesse lorsque l'on rentre la pique dans le mât pour le stockage, sans emmêlement de la chaîne à billes lorsqu'elle est refoulée vers le haut. La longueur totale de la chaîne à billes et de la corde à piano est judicieusement déterminée de sorte qu'en position de repos cet ensemble de transmission soit sans mou et sans jeu.  At the bottom of the spade is fitted a sleeve Rep.ll containing the trigger system consists of the slider Rep.4 with the return spring Rep.5, all closed by the cover Rep.12 blocked by the screw Rep.15. The guide in translation of the slide is provided by the screw Rep.14 whose end pin is housed in the groove Rep.20. A chain Rep.6 made by a series of links or articulated joints or balls transmits the movement of the head of the slide at the bottom of the piano wire. This configuration of links made of hinges articulated between it, offers the advantage of perfect flexibility when entering the spike in the mast for storage, without entanglement of the ball chain when it is pushed upwards. The total length of the ball chain and the piano wire is judiciously determined so that in the rest position this transmission assembly is without slack and without play.
Le mode de fonctionnement du parasol de sécurité pour le vent à déclenchement par le bas de la pique est illustré par la Fig.2. Au repos, le poids du parasol écrase le ressort, et le coulisseau se trouve en position de butée haute au sein de son fourreau. Dès que le vent tend à soulever le parasol, ce ressort précontraint, se détend et repousse le coulisseau vers le bas, entraînant l'ensemble de transmission de mouvement constitué par la chaîne à billes Rep.6 et la corde à piano Rep.7. Cette dernière fait pivoter la came Rep.8 qui, prenant appui sur la paroi interne du mât, translate horizontalement la gâchette Rep.9, laquelle comprime son ressort de rappel Rep.10 pour assurer en final la fermeture automatique du parasol. The operating mode of the safety sunshade for the wind at the bottom of the spike is illustrated in Fig.2. At rest, the weight of the parasol crushes the spring, and the slider is in the high stop position within its sheath. As soon as the wind tends to lift the umbrella, this prestressed spring, relaxes and pushes the slide down, causing the entire motion transmission consisting of the ball chain Rep.6 and the piano string Rep.7. The latter rotates the cam Rep.8 which, resting on the inner wall of the mast, horizontally translates the trigger Rep.9, which compresses its return spring Rep.10 to ensure the final automatic closure of the sunshade.
A l'inverse, pour la mise en configuration d'utilisation du parasol, le mode opératoire est le suivant: le système de déblocage Rep.3 est relâché, la pique télescopique Rep.2 est extraite jusqu'à atteindre sa butée de fin de course réalisée par la bague Rep.17 qui comporte des languettes élastiques Rep.19 venant enserrer radialement la pique qui comporte une gorge annulaire Rep.16 prévue à cet effet et ainsi d'être complètement déployée et auto-bloquée à la longueur optimale, correspondant à la mise à longueur sans mou et sans jeu de l'ensemble de transmission de mouvement chaînette et corde à piano. Le parasol est ainsi posé verticalement sur sa pique et son propre poids suffit à comprimer le ressort Rep.5 par le coulisseau Rep.4, autorisant l'ensemble de transmission à induire le pivotement de la came en position repos, ainsi la gâchette Rep.9, repoussée par son ressort de rappel Rep.10 peut s'extraire radialement afin que l'ombrelle se verrouille automatiquement après avoir été déployée. Pour le rangement du parasol lorsqu'il est refermé, montré en Fig.3, la pique Rep.2 est rentrée complètement à l'intérieur du mât Rep.l jusqu'à venir en butée sur l'ergot Rep.13, la chaîne à billes Rep.6 étant refoulée sans risque de s'emmêler. Ensuite le système de blocage Rep.3, similaire aux systèmes utilisés sur les parasols conventionnels soit par vis de pression Rep.19, soit par levier à came excentrique, est actionné pour immobiliser la pique pendant cette phase de stockage.  Conversely, for setting up the use of the parasol, the operating mode is as follows: the releasing system Rep.3 is released, the telescopic spike Rep.2 is extracted until reaching its end stop. race carried by the ring Rep.17 which comprises elastic tongues Rep.19 radially enclosing the spike which has an annular groove Rep.16 provided for this purpose and thus to be fully deployed and self-locking to the optimum length, corresponding at the length without slack and without play of the whole chain and piano rope. The umbrella is thus placed vertically on its spike and its own weight is sufficient to compress the spring Rep.5 by the slider Rep.4, allowing the transmission assembly to induce the pivoting of the cam in the rest position, so the trigger Rep. 9, pushed back by its return spring Rep.10 can be extracted radially so that the umbrella locks automatically after being deployed. To store the sunshade when closed, shown in Fig.3, the spike Rep.2 is retracted completely inside the mast Rep.l until it comes to stop on the pin Rep.13, the chain Ball Rep.6 being rejected without risk of getting tangled. Then the locking system Rep.3, similar to the systems used on conventional parasols either by pressure screw Rep.19, or by eccentric cam lever, is actuated to immobilize the spike during this storage phase.
Une variante de l'invention montrée sur la Fig.4 concerne un parasol ne possédant pas de pique et s'appuyant directement sur son mât Rep.l. Dans ce cas le système de transmission est simplifié au niveau du système de transmission pouvant être réalisée par un simple lien Rep.21 reliant directement la tête du coulisseau Rep.4 à la came Rep.8. A variant of the invention shown in Fig.4 relates to a parasol that has no spike and leaning directly on its mast Rep.l. In this case the transmission system is simplified at the level of the transmission system can be achieved by a simple link Rep.21 directly connecting the head of the slide Rep.4 to the cam Rep.8.
